Another attempt to structure processes.

To make this hands-on useful, it is mostly documented in the code.

Here are some interesting invocations of pypes-example.py.

$ ./pypes-example.py
...
$ LOGLEVEL=DEBUG ./pypes-example.py
...
$ LOGLEVEL=debug STDOUT_LOGLEVEL=error ./pypes-example.py
...
$ LOGLEVEL=debug STDOUT_LOGLEVEL=info ERROR_LOGFILE=error.log ./pypes-example.py
...
$ STDOUT_LOGLEVEL=success WARNING_LOGFILE=warn.log ./pypes-example.py
...

The ideas is very general. pypes-example.py contains an example (that could still be revisited to point out the idea more). It was intended to structure "long" comutational processes into reusable elements.

The file logsetup.py can also be use stand-alone.
